摘要：

We have observed the band structure and Fermi surfaces of the heavy Fermion superconductor UPd2Al3 by angle- resolved photoemission experiments in the soft X- ray region. We observed renormalized quasi- particle bands in the vicinity of the Fermi level and strongly dispersive bands on the higher binding energy side. Our observation suggests that the structure previously assigned to contributions from localized states in the U 5f spectrum has strong energy dispersions. (c) 2006 Elsevier B. V.
